IPC: G06T11/60
Filed: 1991-06-17
Abstract: PURPOSE:To offer an image data processing method capable of initializing the contents of a memory without complexing processes. CONSTITUTION:Ruled line data corresponding to the raster of image data out of plural ruled line data corresponding to one raster which are stored in a soft form memory 142 ate written in a page buffer 150 to form a ruled line pattern.

Title: Formation of ohmic electrode on oxide semiconductor
Inventor: TAMURA YASUTAKA
IPC: H01L21/60
Filed: 1991-06-18
Abstract: PURPOSE:To enable an ohmic contact possessing a low resistance to be formed on an oxide semiconductor having a high dielectric constant by bonding a semiconductor, made of a metal which tends to be readily oxidized, directly to the surface of the oxide semiconductor using ultrasonic waves. CONSTITUTION:Metal which tends to be readily oxidized, for instance, an Al line 8a, is pressed against and bonded to the surface of an oxide semiconductor layer 7 with the application of ultrasonic waves. As a result of this, it is assumed that a thin oxide layer 9a of Al is formed on a boundary between Al and the oxide semiconductor by virtue of pressures and high temperatures produced by ultrasonic waves, whereupon a low contact resistance is obtained on the boundary. This oxide layer is as thin as several millimeters, and acts as a thin tunnel barrier layer, whereby a contact possessing a low resistance can be formed between the oxide semiconductor layer and the aluminum lead. Concurrently, the strength of the bonding relative to the oxide semiconductor layer of the lead can be in creased.

Title: Water hammer preventing device
Inventor: YAMADA KAZUO
IPC: C08J5/04
Filed: 1988-06-15
Abstract: PURPOSE:To surely prevent affection of water hammer with a cheap arrangement by providing a bypass channel having a shut-off means, downstream of a water pump, and by providing a control means for opening the sut-off means for a predetermined time upon start of the water pump. CONSTITUTION:When a turn-on switch 3 for a water pump 2 is turned on, a timer relay 6 is energized while an electromagnetic contactor 4 is excited so as to start the water pump 2. Since a solenoid valve 5 is opened for a predetermined time after the start of the water pump 2, water flows through a bypass channel. After a predetermined time elapsing, the solenoid valve 5 is closed, and accordingly, the bypass channel is closed so that water flows only through a heat-exchanger assembly 1. Thus, affection of water hammer upon start of the water pump 2 may be absorbed by the bypass channel so as to prevent the affection of water hammer upon the heat-exchanger assembly. With this arrangement, it is possible to prevent water hammer with a cheap arrangement.

The acute thermal conductivity change is obtained by utilizing the acute metal insulator transfer. It the metal insulator transfer in which the resistivity change does not occur is selected, the great thermal conductivity change may be obtained. When such thermal change layer is used, the width of thermal conductivity decrease regions is determined while a feedback that the generation of the thermal conductivity decrease regions and the temperature rise by the same is repeated. The control of the temperature distribution meeting the width of the thermal conductivity decrease regions is made possible.
